Outline of Final Research Achievements

We conducted a performance verification of the ultrasonic telemetry system (Ultrasonic transmitter attached to fish: a receiver that receives the pin and its signal) under sea ice, which has not been sufficiently investigated so far, and is used for conducting behavioral and ecological observations of fish under sea ice in the Antarctic.
In particular, verification of the operating period at low temperatures. And we did verification and elucidation of whether accurate Pinger position can be measured by the influence of the sound reflected (multiple reflections) on the sea ice because the sea surface is covered with sea ice.

Academic Significance and Societal Importance of the Research Achievements

海水温度が低く、海面が海氷で覆われている環境における超音波テレメトリーの運用はこれまで行われたことが少ない。設置手法や海氷による反射の影響などを明らかにすることで、極限水域でのテレメトリーシステムの活用が見込まれる。低温下での魚類の行動・生態は不明な点が多く、地球温暖化などに大きく影響されることが予想されるので、本成果を活用することで、魚類の行動・生態の新たな知見を得られる可能性を示唆している。
